Always provide the API URL or a link to your pack details page when requesting custom modpack assistance. This contains metadata crucial to a proper analysis.

• Your pack should not contain a /bin/modpack.json file. This will be overwritten by the contents of the modpack.jar every time the pack is launched. Edit the file inside the modpack.jar file if you need to alter it.
• Your modpack.jar file is not correct. The modpack.jar file is simply the correct version of the Forge universal binary JAR file renamed to modpack.jar.
